Stalin and Hitler's Bloody Competition

How much should the cannibalism count? How should we factor it into the growing historical-moral-political argument over how to compare Hitler's and Stalin's genocides, and the death tolls of communism and fascism in general. I know I had not considered it. I had really not been aware of the extent of the cannibalism that took place during the Stalinist-enforced famine in the Ukraine in 1933 until I read Yale University history professor Timothy Snyder's shocking, unflinching depiction of it in Bloodlands, his groundbreaking new book about Hitler's and Stalin's near-simultaneous genocides.
